The bake time for jalapeno poppers is 20 to 30 minutes in a 350-degree oven. This holds true whether you stuff your peppers with cream cheese or cheddar cheese filling and whether you choose to coat them in breading or not. However, if you choose to wrap your stuffed jalapenos in bacon, you’ll want to increase the bake time to 30 to 45 minutes to make sure that the bacon gets fully cooked and crispy. For breaded or bacon-wrapped peppers, you’ll know they’re done when they’re nice and crispy; for recipes without a coating, look for the cheese inside to get browned and bubbly.
